Harvard Business Review published this article and what caught my eye was the section on "deep level diversity". We all think of gender, age, disability when the topic is raised but there is the area of psychological that needs to be considered. So if like me your were not aware of this particular angle then read the full article and add this to your appreciation of the diversity agenda.
Deep-level diversity is key. Most discussions about diversity focus on demographic variables (e.g., gender, age, and race). However, the most interesting and influential aspects of diversity are psychological (e.g., personality, values, and abilities), also known as deep-level diversity. Indeed, there are several advantages to focusing on deep-level variables as opposed to demographic factors. First, whereas demographic variables perpetuate stereotypical and prejudiced characterizations, deep-level diversity focuses on the individual, allowing a much more granular understanding of human diversity. Regardless of whether you focus on bright- or dark-side personality characteristics, motives and values, or indeed creativity, group differences are trivial when compared with differences between individuals, even when the individuals are part of the same group.
